Yie Ar Kung-Fu

Oolong (or Lee in the MSX and Famicom versions) must fight all the martial arts masters given by the game (eleven in the arcade version; five to thirteen in the home ports). The player faces a variety of opponents, each with a unique appearance and fighting style. The player can perform up to 16 different moves, using a combination of buttons and joystick movements while standing, crouching or jumping. Moves are thrown at high, middle, and low levels.

Regardless of the move that defeated them, male characters (save Feedle) always fall unconscious lying on their backs with their legs apart (Oolong flails his legs), and female characters always fall lying on their sides. Feedle disappears. When a player gains an extra life, the word " xiè xiè " (Mandarin for "thank you") is heard. Instead of a point-scoring system like Karate Champ (1984), Yie Ar Kung-Fu instead introduces a health meter system.

Each fighter has a health meter, which depletes as they take hits. Once a fighter's health meter is fully depleted, it leads to a knockout . On the arcade version, players can play on until all their lives are gone. No bonus lives are given thereafter once 9,999,900 is scored.
